Hearing Aid Batteries Drain Quickly Because of This

Button battery for hearing aids on the brown wooden table. The object is on the left. The batteries are stacked in a triangle.

Do your hearing aid batteries seem to die faster than they ought to? There are several reasons why this might be taking place that might be surprising.

So how far should the charge on my hearing aid battery go? The ordinary hearing aid battery lasts anywhere from 3 to 7 days.

That’s a really wide range. But it’s so wide that it’s unpredictable and may leave you in a bind.

You could be on day 4 at the grocery store. Out of the blue, you can’t hear anything. The cashier is speaking to you but you don’t hear what they are saying.

Or it’s day 5. You’re appreciating a night out with friends. Suddenly, you find yourself feeling really alone because you can no longer hear what your friends are saying.

Perhaps you go to your grandchild’s school to watch a play. And the children’s singing goes quiet. But it’s only day 2. Yes, occasionally they even die before that 3-day mark.

It isn’t simply inconvenient. You have no clue how much power is left and it’s causing you to miss out on life.

Here are 7 possible causes if your hearing aid batteries drain quickly.

Moisture can drain a battery

Did you realize that human beings are one of the few species that release moisture through their skin? It’s a cooling system. It also helps clear the blood of excess toxins and sodium. Your battery may be subjected to even more moisture if you live in a humid or rainy place.

The air vent in your device can become clogged by this extra moisture which can cause less efficient functionality. It can even drain the battery directly by interacting with the chemicals that generate electricity.

Prevent battery drain caused by moisture using these steps:

  • Take the batteries out if you’re storing them for a few days
  • A dehumidifier is helpful
  • Open up the battery door before storing the hearing aids
  • Store your hearing aids in a place where moisture is minimum

Advanced modern features are power intensive

Current digital hearing aids help people hear so much better than ones that came out just 10 years ago. But these extra functions can cause batteries to drain more quickly if you’re not watching.

That doesn’t mean you shouldn’t use these amazing features. But be aware that the battery will drain faster if you spend all day streaming music from your phone to your hearing aids.

Noise-canceling, Bluetooth, multichannel, tinnitus relief — all of these added functions can drain your battery.

Altitude changes can impact batteries as well

Your batteries can be drained quickly when you have a rapid climb in altitude, and if they’re already low this is particularly true. When flying, skiing, or climbing remember to bring some spares.

Perhaps the batteries aren’t actually drained

Many hearing aids will warn you when the batteries need to be changed. These warnings, as a general rule, aren’t telling you that your batteries are dead, they’re simply a heads up. Moreover, sometimes an environmental change in altitude or humidity temporarily causes the charge to dip and the low battery alarm will sound.

Take the hearing aids out and reset them to quiet the alarm. You might be able to get several more hours or even days from that battery.

Incorrect handling of batteries

You should never pull off the little tab from the battery before you’re ready to use it. Always wash your hands before handling your hearing aids or batteries to avoid getting hand oil or dirt on them. Don’t ever freeze hearing aid batteries. This might increase the life of other batteries but that’s not the case with hearing aid batteries.

Hearing aids will drain faster if you mishandle them in these ways.

Buying a year’s supply of batteries isn’t a good idea

It’s often a practical financial decision to buy in bulk. But you can expect that the last several batteries in the pack will drain faster. It can be a waste to buy any more than a 6 month supply.

Buying hearing aid batteries from the internet

We’re not claiming it’s automatically a bad idea to buy things online. You can find a lot of bargains. But you will also find some less honest sellers who will sell batteries that are near to or even past their expiration date.

Most kinds of batteries, including hearing aid batteries, have expiration dates. You wouldn’t purchase milk without checking when it expires. You shouldn’t forget to check the date on batteries either. Make sure that the date is well in the future to get the most use out of the pack.

If the website doesn’t declare an expiration date, message the seller, or buy batteries at a pharmacy or hearing aid store where you can see it on the box. Only purchase batteries from trustworthy sources.

Hearing aid batteries drain quickly no longer

Hearing aid batteries might drain more quickly for several reasons. But by taking little precautions you can get more power from each battery. And if you’re thinking of an upgrade, consider rechargeable hearing aids. You put these hearing aids on a charger every night for an entire day of hearing the next day. The rechargeable batteries only have to be swapped out every few years.
